VERNON BOYLE, OF PATTERSON, NEW JERSEY.

CIRCULAR 1100M.

To all whom it may concern: a y,

Be it known that I, VERNON Home, a citizen of the United States, and resident of Paterson, in the county. of Passaic andSta-te of. New Jersey, have invented a new and useful Improvement in Circular Looms, of which the following is a specification.

My invention relates to circular looms and more particularly to theweavingfpin and parts intimately associated therewith, with the object in view of providing improved 'parts immediately associated means for adjusting the weaving pin either laterally or vertically within its support,

and further, for adjusting the weavlng' point or weaving port.

My invention further contemplates a weaving pin and weaving pin carrier with their several adjustments complete in itself, the whole constituting a self-contained unit which can be used not only upon a loom built specifically for the purpose, but upon circular looms of different general constructions. 7 a v In the accompanying drawings, Figure 1 a top plan view of the weaving pin and therewith, partly broken away to show the position of one of the screws for centering the weaving pin carrier and hence the weaving pin carried thereby. Fig. .2 is a view of the pin carrier in a fixed supsame inside elevation. Fig. 3 is a vertical of the line (I -G of Fig. 8.

. provided with bolt holes 2 for securing it section in the plane of the line AA of Fig. 1. Fig. 1 is a partial vertical section in the plane of the line 13-13 of Fig. l, and Fig. 5 is a partial horizontal section in the plane The base or main supporting pin structure 1s denoted by 1, shown of circular form and 1s piece of the and is here conveniently fixedly to a circular loom in substantial a-Xial'alinement'with the center column or support of the loom, such, for example, as the loom shown, described and claimed in mypending application Serial No. 665991, filedDecember 15, 1911. The fixed support 1 is a ring and has on its interior face a screw-thread 3, which registers with an external screw-thread4 on an annular nut 5, which carries the weaving pincarrier 6, in which the weaving pin is supported.

The weaving pin carrier 6. is provided or ledge 8 which rests on an annular shoulc er 9, formed on the interi'or face of the nut 5, sothat as 1711?, But if) Specification of Letters Patent. Patented Sept. 14, 1915. Application filed August 22, 1914 Serial No. 58,108.

is moved up and down by turning it within the screw threaded base 1, the weaving pin carrier "6 and thepin 7 carried thereby, will be raised and lowered. To look the nut 5 and the parts carried thereby in the desired vertical adjustments, plungers l0 and 11 on diametrically opposite sides of the base 1, i

areseated respectively in bores 12 and 13, tapped horizontally-through the base 1, the outer end of each plunger 10, 11, being formed conical, as shown at 14c, and these conical outer ends of the plungers are engaged'by the conical ends 15 of adjusting screws 16, 17, tapped from the upper face of thebase 1, through into the bores 12 and 13.. Those'portions of the base 1 which receive the screws 16,17, are conveniently thickened to form suitable bearings for the screws.

It will be observed that the structure is such that when the screws 16, 17, are screwed downwardly, they will force the .plungers 10,11, laterally into engagement with the screw-thread 1 on thenut 5, and hence lock the nut against a rotarymovement. When it is desired to rotate the nut, these screws 16, 17, are unscrewed, permitting the plungers torecede from the screw-thread 4, or at least to offer no pressure suflicient to prevent the nut 5 from turning. The outer ends of the bores 12 and 13 are conveniently closed by plugs 18.

The weaving pin carrier which carries the weaving pin 7, is allowed suflicient lateral play within the nut 5, to permit of centering the weaving pin carrier with reference to the center of weaving, and this centering of the weaving pin carrier 6, is accomplished by means of four screws 19, 20, 21, 22, conveniently located a quadrants distance apart and having a screw-threaded engagement with holes formed in the body of the nut 5.

The weaving pin carrier 6 is hollow and the lower portion thereof is provided with an interiorscrew-thread 23 which interengages an externaltoothed screw-thread 2 1- ormed on the lower portion of the weaving pin 7. The .threads 23, 24, are preferably flat faced and the teeth on the thread 2 1 of the weaving pin 7 form a rack which is engaged byoa pinion 25, seated in avertical socket 26,.the lower end of the pinion being journaled in the bottom wall of thesocket 26 and the upper end of said pinion being journaled in a journal box 27 fitted in the upper end of the socket 26. The upper jourm1 ofthe pinion 25 is provided with a ,kerf

28, so that the pinion 25 may be turned by strument.

preferably made sufficiently long to engage r the rack on the screw 24, at each convolution means of a screw-driver or other suitable in The teeth on the pinion 25 are 'its radial movement 1n engagement with ;the internal thread 23 on the weavingpin carrier.

-' The weaving pin 7 is hollow or tubular and its upper portion is fitted so as to slide with a close sliding fit in the upper end of.

the weaving pin carrier. 7

To look the Weaving pin against anytendency to rotate within the weaving pin carrier 6, after it has been adjusted to the desired" elevation within the carrier, a screw 30, is set in the wall of the weaving pin carrier 6, inproximity to the upper journal of the pinion 25, sothat the head of the screw will lap over a portion of the journal" box clearly shown in Fig. 1, and when the screw is screwed inwardly, the journal box 27 will press the' pinion 25 endwise against its lower bearing, producing sufficient friction to hold it against unintentional rotary movement. hen it is desired to r0- tate the pinion 25, the screw 30 is loosened.

For convenience in turning the nut 5'in the base 1, the rim of the nut may be pro vided with holes 29, at suitable intervals in which the end of a small operating lever may be inserted.

.The foregoing structure provides for elevating and lowering the weaving pin carrier 6 and the weaving pin 7 carried thereby, by turning the nut 5 in the base 1 and the nut 5 may be locked with the parts carried thereby in its adjusted position by the screws, 16, 17 Furthermore, the weaving pin carrier and weaving pin carried thereby, may be centered with respect to the axis of weaving by moving it horizontally within the nut 5 and locking it in position by means of the screws 19, 20, 21, 22. The weaving pin may be further adjusted vertically relative to the weaving pin carrier, leaving more or less of thepin 7 exposed abovethe carrier 6, to'increase or decrease the friction on the woven tube by unlocking the pinion 25 and turning it in the one direction'or the other andthereby screwing the pin 7 up or down within the carrier 6. This structure provides means for accurately adjusting the weaving pm by means 1n close assoclation with the pin, and the pm and the parts 1mmediately connected therewith are so arranged that they form a weaving pin unit capable of application to circular looms 2. A tubular weavlng .pin provided with already manufactured as well as to looms the weaving pin an external screw thr'ead,f.a}weaving pin:
